Techniques would most usefully be called those fixed patterns of movement that are specific to a circumstance and that we work to automate as a response to that circumstance, i.e. foot there, arm there, step over there, lower here, turn there...

General qualities, those things which it is a disservice to label as technique, are those which can be applied almost universally to movement/combat scenarios, which we seek to train under broader and broader scope rather than limit them to fixed circumstance, i.e. structure, relaxation, tension, explosiveness, rapidity of change, reactiveness, suddenness, etc.
